I have mouth ulcers in my mouth and tongue, pain in the neck and right ear. Is it cancer? Which doctor, should I consult first?

It is not necessary that all mouth ulcers lead to cancer. They have multiple causes like a viral infection or stress. I am sure that it is not cancer. But to be on the safe side, it is best that you consult a doctor. To start with, you should contact your family physician who will guide you about your condition. Further, he may refer you to an Oncologist, if he feels you have cancer. Mouth cancers are usually treated by a Surgical Oncologist or a Maxillofacial surgeon having experience in head and neck cancer treatment.
